Hodges, 20, and Reid reportedly dated for five years before their relationship ended last week.

A witness told police that Hodges tried to run but Reid allegedly shot her in the back as she fled with their child.

Minutes before the alleged murder, cops say Reid posted what appeared to be an apology to Facebook.

"I’ve been pushed to this point over time," he wrote, according to WSMV. "It’s so sad. I’m a terrible person overall."

Allen County EMS responded and found Hodges on the porch of the home with a gunshot wound. She was transported to a hospital, where she later died, according to a statement from the Allen County Sheriff's Office.

Scottsville Police Department Detective John Rose told InsideEdition.com that Reid told his mother he intended to kill himself following the murder. However, that attempt was interrupted, Rose said.
